Click for larger | Amazing what a difference a millimeter makes! While 3.5mm was the standard for electrical gear for a long time, there are more and more 2.5mm units coming on the market, and if your toys are one thing, and your power unit is the other, you are SOL. So here's the situation. You have a toy, and the plug looks like what you see in the photo, but you can't get it into the hole (in your power unit - get your mind out of the gutter), your toy has a 3.5mm plug, and your power unit has a 2.5mm jack. Order the 536, which is 3.5mm female to 2.5mm male. Conversely, you have a toy and you try and plug it in, but the hole is too big and it wiggles around (not even going to comment on that one), your toy has a 2.5mm plug and your power unit has a 3.5mm jack. Order the 563, which is a 2.5mm female to a 3.5mm male. . |
